Reverting this change in r19668, line 700:
begin
{ Constructors need the destroy-on-exception code even if they don't
use managed variables/temps. }
//if (cs_implicit_exceptions in current_settings.moduleswitches) and
// (is_class(procdef.struct) and (procdef.proctypeoption=potype_constructor)) then
// maybe_add_constructor_wrapper(code,true)
//else
maybe_add_constructor_wrapper(code,false);
addstatement(newstatement,loadpara_asmnode);
Makes everything work fine again. The if..else was added by you in
19668. Maybe a forgotten situation to generate stackframe ?
